Worst service

It's 4am I'm receiving a debit check mandate to accept. I ain't accepting that mandate at all. First you debit me ab incorrect amount after laying my complaint and advising I no longer need yours services and send me a message to accept a debit check, cancel means stay away from. I was never interested from the beginning National moved me to you and currently you not helpful. The device is not working I must pay for technician hybo I ain't doing that. I need your service cancelled, and stay away from my account .
